Carrier Aggregation (CA) is one of the promising features to support the much wider bandwidth for packet transmissions in Long Term Evolution-Advanced (LTE-A) systems. To the best of our knowledge, works regarding the packet scheduling algorithm in LTE-A systems with the CA mechanism have not thoroughly been investigated yet till now. In this paper, we(More)
Carrier Aggregation (CA) is one of the promising features in Long Term Evolution-Advanced (LTE-A) systems. Till now, works regarding the packet scheduling scheme with CA in different frequency bands have not completely been studied and evaluated yet. Thus, the purpose of this work aims to explore such issue and presents an efficient quantized water-filling(More)
Due to the fact that existing 3.5G network cards usually select networks with the highest data rate as their priority choices, the radio resources may not be efficiently and equally utilized in a multiple network environment, even when the network with the highest rate is already congested. In this paper, we propose two dynamic resource allocation(More)
As mobile data traffic levels have increased exponentially, resulting in rising energy costs in recent years, the demand for and development of green communication technologies has resulted in various energy-saving designs for cellular systems. At the same time, recent technological advances have allowed multiple component carriers (CCs) to be(More)
